For sale is my Breeze Audio DI-U8, purchased November 2015. It is a near mint, fully functional unit, based around the excellent XMOS U8 chip. It has a USB input, and coaxial, optical, I2S and AES/EBU outputs.
It has the upgraded Talema transformer here - http://ebay.to/2jWIOxE
It's been one of the best USB converters out there and I far prefer it to something like the Gustard U12.
